If I were to describe it to you, I'm certain it would sound even more alien, but it's called "in vitro fertilization," and it's an extensive but incredibly safe procedure, with a rather high success rate.

[ At this point, she's content just to be led around by the hand and talk science. Better to infodump than to talk about more complex matters. ]

To simplify it as much as possible, let's say, for example, we were to get the procedure done, just as a hypothetical. So I would first be given medication that would stimulate egg production in my body, and the eggs would be extracted through a minor surgical procedure. Those eggs would then be placed in a glass dish and be fertilized by reproductive material from an anonymous donor, as there are many facilities set up specifically to collect that material. So my fertilized egg, now considered an "embryo," would then be transferred into your body through a small tube, and you would carry the child to term, and, viola, you have an heir.

It's a procedure that's often used in the event that there are complications with a pregnancy, but, it gets the job done.
